I have 6 pachages of yarn using a #10 crochet hook what size throw can a make(double crocheting)?

I used to crochet a lot when we lived up North(long cold boring winters) but not since we moved to Florida and I just found 6 unused packages of yarn and a #10 hook and I can't figure out what size throw this may make if I double crochet..maybe even use 2 packages(skeins) at once on the hook. Thanks :o))
